Morever, despite the presence of angular momentum in the two independent spatial hyperplanes, the solution has no ergo-region (\(g_{tt}<0\)  always), so no (near) super-radiant modes are present in the spectrum. The absorption cross section is zero, while it is non-vanishing for the small BH. We also point out differences in the tidal deformability both in the static (\(\omega =0\) ) and non-static (\(\omega \ne 0\) ) case. Such a comparison between `small' BHs and `stringy' micro-states is very intriguing and, combined with analysis of chaotic behaviour in scattering amplitudes involving highly excited string states
[1]}, [2]}, [3]}, [4]} or in BH dynamics [5]}, [6]}, [7]} should pave the way to further our understanding of the string-BH correspondence [8]}, [9]}.
